As the central character in the movie "Blood Diamond" the Rhodesian
Solider of Fortune (played by Leonardo DiCaprio) in the says when he
is having a bar conversation with an the American Women (Jennifer
Connelly) :

DiCaprio: “Don’t tell me you’re here to make a difference.”

Connelly: “And you’re here to make a buck?”

DiCaprio: “I’m here for lack of a better idea.”

Connelly:“That’s a shame.”

DiCaprio: “Not really. Peace Corps types only stay around long enough
to realize they’re not helping anyone. Government only wants to stay
in power until they’ve stolen enough to go into exile somewhere else.
And the rebels, they’re not sure they want to take over, otherwise
they’d have to govern this mess. But TIA, right M’Ed?"

Time travel. It'll turn your brain into spaghetti if you let it. Best not to think about it. Best just to get on with the job in hand. Which is destroying the enemy before they're even born and have a chance to threaten us. We're expecting any resistance to be light, because the ancestors of our enemies have yet to evolve any thumbs... or indeed spines. But that does not change the fact that they may one day evolve into a species that may pose a threat to us. And for that reason, we are going to rain down a fiery death upon them that will turn the surface of their planet into a radioactive desert! Because we are the planetary peace corps! And that is what we do! Now, are you nappy-wearing motherfuckers ready to lock and load, and *get it on*?

That was the summer of 1963 - when everybody called me Baby, and it didn't occur to me to mind. That was before President Kennedy was shot, before the Beatles came, when I couldn't wait to join the Peace Corps, and I thought I'd never find a guy as great as my dad. That was the summer we went to Kellerman's.

Violet, that is so cute! Now lemme tell you about me. My name is Wendy and I first moved to New York when I was 21 to be a dancer, but I broke my big toe and then I got knocked up by this actor who dumped me to join the Peace Corps, so for the last 16 years I been raising my daughter all by myself and then two weeks ago, she tells me that she is a bisexual and that she hates me more than any person on this planet.

'Dear Dad. Have made terrible mistake and joined the Peace Corps. Please arrange to have me brought home at once. Your loving son, blah, blah, blah Lawrence'.
Yep; never seen anything like it. Waiver of training, physical, background check; immediate assignment to the Peace Corps at Loon Ta.
What! Loon Ta! You mean I'm in the Peace Corps? There, there must be some mistake!
